PORTABLE ELECTRIC LAMP.
SPECIFICATION forming part of Letters ZPatent No. 599,975, dated March 1, 1898.
Application iiled July 8, 1897. Serial Noi 643,807. (No model.)
To @ZZ whom it may concern:
Beit known that I, LEONARD PAGET, a citizen of the United States,residing at New York,
in the county of New York and State of New York, have made a new and useful Invention in Portable Electric Lamps, of which the following is a specification.
My invention relates particularly to iinprovernents in that type of portable electric lamps which utilize batteries as the source of current-supply-such, for instance, as are used in connection with hand lamps or lanterns, bicycles, carriages, and analogous vehicles 3 and itsobjects are, iirst,to devise such a lamp as will be compact in structure, with the parts and circuit connections so arranged or constructed that they will withstand` the ordinary shocks and usage in transportation without detriment thereto; second, to so arrange said parts that the batteries may-be quickly and readily removed from the retaining-casing when it becomes necessary to restore or replenish them; third, to construct the supporting` parts of the battery in the nature of metallic casings,and to combine therewith a lamp and a reflector in such manner that the casings constitute the conductors of the current from the battery to the lamp, thereby avoiding the use of wires as conductors.
My invention will be-fully understood by referring to the accompanying drawings, in which- Figure 1 is a side elevational view of the entire structure, and Fig. 2 aplan view of the top portion thereof. Fig. 3 is a vertical sectional view taken through Fig. 1, the reflector being shown in broken section. Fig. 4 is a horizontal sectional view taken on the line Q3 0c, Fig. 3, the reector and lamp being removed.
Referring now to the drawings in detail, A and A' represent two tubular metallic retainingcasings, and K and K metallic heads or caps therefor, provided with bayonet-andsocket connections, the pin connection being attached to theinner portions of the retainingcasings and the bayonet connection grooved in the outer surface of the heads or caps K and K', as will be obvious on inspection of Fig. 8.
C represents a cylindrical clamp or clip, provided on one side with two lugs or ears L and on the other with a neck N, screw-threaded interiorly for the purpose of receiving the screw-threaded neck S of a metallic reflector R, which neck in turn is provided with an opening and interior screw-threads adapted to receive the screw-threaded portion of an incandescent lamp L.
B and B represent two metallic battery* cups, preferably of copper, for retaining the battery solution, and E E are the active electrodes, hermetically sealed therein, said electrodes being of any preferred form, either in the nature of a dry battery or a storage battery of any preferred structure, the retaining-cups B and B constituting the positive poles of the battery and the electrodes E E the negative poles thereof, the arrangement being such that when the solution is in position in the hermeticallysealed cups and the cups in turn in position in the retaining-casings A and A the lower cup B will rest upon the inner surface of the bottom cap K and the upper cup B will rest upon the negative electrode E of the lower cell, P beinga metallic thumb-screw adapted to be screwed through the upper cap K against the electrode E, R being a softrubber ring for effectually sealing the upper portion of the battery.
The inner and outer surfaces of the casing A are coated with insulating material, preferably a thick coating of japan, and the outer surface of the lower casing A is similarly coated to a point near the lower edge of the clamp O, the coating being discontinued at this point for the purpose of making good electrical connection between the outer surface of the casingA and the said clamp O, as clearly illustrated in Fig. 2 of the drawings.
s is a conducting-spring secured to the lower end of the metallic casing A but beneath the insulating-coating, its free end being adapted to bear against the inleading conductor of the lamp L, the outleading conductor of which is connected to the screw-threaded portion of the lamp and hence to the conducting-necks S and N, the circuit being from the inleading conduct-or of the lamp through the spring 3, the metallic shell A', cap K', screw-plug l?, electrode E, through the battery solution from the cup B to thev lower inner electrode E, thence through the battery solution of the IOO lower cup B to said cup, finally through said cup to the lower cap K, to the retaining shell or casing A, back to the neck N in the screwthreaded portion of the lamp through the filament to starting-point.
In order to put the parts together, the screws in the rear side of the clamp or clip C are simply removed and the casings A and A inserted in the manner shown in Fig. 3, after which the screws are driven firmly home, so as to firmly clamp or clasp the shells in the position shown. The lamp, and its reiiector, is then screwed into the neck N and is ready for use. Then it is desired to disconnect the lamp, it is only necessary to withdraw the thumb-screw P until the circuit is broken.
I do not limit myself to the especial details of construction herein shown and described, as the same might be departed from in a number of respects and still come within the scope of my claims herein after made. To illustrate, the heads or caps K and K might be screwthreaded and the interior of the cups correspondingly screwthreaded to receive the same, or the tubular retaining casings or shells A and A might be made each of a single piece of metal of cup-like form, the upper one having the opening for the thumb-screw P or any analogous switch which might be used for closing and interrupting the circuit, the lower or open end of the upper retaining-casing A and the upper end of the lower retaining-casing A being provided with bayonet-pins adapted to iit into bayonet-grooves in the body part of the clamp C, the necessary insulation of course being provided for the upper cup for I the purpose of insulating it from said clamp,
my invention being directed generically to a portable lamp having two retaining-casings inclosing the necessary battery and held together by retaining means which supports an electric lamp in circuit with the battery.
It is obvious that there may be more than two battery-cells used in the manner hereinbefore described and that they might be placed side by side instead of the one upon the other, and also that the retaining-casing might be of any conducting material and insulated on its exterior surface wholly by enamel or otherwise, as desired.
Having thus described my invention, what l claim, and desire to secure by Letters Patent of the United States, is
l. An electric lamp consisting` of a case comprising two parts of conducting material insulated from each other and covered with external insulation, a lamp supported upon the case, and electrically connected thereto, and a battery within the case, one of its terminals being in engagement with one part of the case, and the other adapted to be connected with the other part thereof by means of a movable circuit-closer, substantially as described.
